Endovascular radiofrequency obliteration using 90 degrees C for treatment of great saphenous vein.

The recommended treatment temperature for endovascular radiofrequency obliteration (RFO) of the great saphenous vein (GSV) is 85 degrees C. Faster catheter pullback rates are possible when the operating catheter tip temperature is increased. We studied the safety and effectiveness of RFO of the GSV using a temperature of 90 degrees C, tumescent infiltration, and catheter pullback rates double the current standard.

Long-term outcomes of endovenous radiofrequency obliteration of saphenous reflux as a treatment for superficial venous insufficiency.

Background: Endovascular radiofrequency obliteration has been used as an alternative to conventional vein-stripping surgery for elimination of saphenous vein insufficiency. A clinical registry was established in 1998, and its mid-term results have been reported previously. This study is to demonstrate the long-term treatment outcomes and to determine the risk factors that affect treatment efficacy.

Four-year follow-up on endovascular radiofrequency obliteration of great saphenous reflux.

Background: Endovascular radiofrequency obliteration has been used since 1998 as an alternative to conventional vein stripping surgery for elimination of saphenous vein insufficiency.

Objective: To demonstrate the long-term efficacy of this treatment modality.

Methods: Data were prospectively collected in a multicenter ongoing registry.

Duplex ultrasound scan findings two years after great saphenous vein radiofrequency endovenous obliteration.

Objective: To assess the clinical and duplex ultrasound scan findings in the groin and thigh 2 years after great saphenous vein (GSV) radiofrequency endovenous obliteration (RFO).

Methods: Sixty-three limbs in 56 patients with symptomatic varicose veins and GSV incompetence were treated with RFO, usually with adjunctive stab-avulsion phlebectomies, and examined at a median follow-up of 25 months, by using a color-coded, duplex sonography protocol that mandated views in at least two planes of the saphenofemoral junction (SFJ) and its tributaries and at three GSV levels in the thigh.

Results: The commonest duplex finding in the groin was an open, competent, SFJ with a < or =5-cm patent terminal GSV segment conducting prograde tributary flow through the SFJ (82%).

Endovascular obliteration of saphenous reflux: a multicenter study.

Objective: The objective of this study was to assess the differences in clinical outcomes in patients treated with endovenous saphenous vein obliteration with technical outcome of either complete occlusion (CO), near complete occlusion (NCO), defined as < or =5-cm segment of flow in treated vein, or recanalization, defined as >5-cm segment of flow in treated vein.

Study Design: The study was designed as a prospective registry with follow-up at intervals through 24 months. The subjects were 286 patients from 30 clinical sites with saphenous vein reflux as measured with duplex scanning.
